Animals in Fall: Preparing for Winter is a nonfiction picture book teaching young readers about some of the changes that happen in autumn.  This book is divided into five chapters, each with a specific theme, and has a table of contents, glossary, and index.  What I like particularly about this book is that it groups animals into three categories: those that migrate, those that hibernate, and those that change, and gives beautiful examples of each category.  This book is a terrific way to study seasonal changes as well as introduce nonfiction books.
